Scottish government's latest announcement.
Scotland’s First Minister today announced that new petrol and diesel vehicles will be phased out in Scotland by 2032 – eight years ahead of the rest of the UK. There is also to be a significant expansion in the charging network, including an Electric Highway along the A9, Scotland's longest road.
Scotland’s four biggest cities will have Low Emission Zones, banning the most polluting vehicles, by 2020. The Scottish government is already committed to one Low Emission Zones by the end of next year. Let’s see what happens with that. Kind of goes against their North Sea Oil stance of the Independence Referendum. |
How are they going to generate all of that electricity?

Maybe they can buy it from Iceland.

I was going to say buy electrical power from some where else.

But anyway, with all this worldwide trend on a ban of petroleum-based fuels (and eventually fossil natural gas) for road transportation, I'd still not hold my breath for any all-electric approach. Biofuels might play an important role, eventually resorting to the enhanced fuel-economy of plug-in hybrid drivetrains in order to address both concerns about fuel supplies and the side-effects of eventual power shortages (maybe the vehicle could eventually supply energy to the household, like a genset, during emergencies). |

Even though there is a good potential for clean electric power generation there in Scotland, I still believe internal-combustion engines are going to retain a role when it comes to close the carbon cycle. Due to all the methane generated by decomposition of organic matter in landfills and sewerage treatment plants, it would make more sense to use it as an energy source instead of just venting it directly into the atmosphere, considering that it has a longer half-life as a greenhouse gas compared to carbon dioxide.

There are a couple of Landfill sites near me where it is tapped off. Where it goes after that, I have no idea.
One of the Orkney islands, Eday, has a tidal generator that develops more energy than the island can use. Because Eday is not connected to other islands they have to turn the electricity into H2, which they can ship off to the Orkney mainland. It is used in fuel cells to power the auxiliary systems on the ferries, while they are in port. Once they have suitably accredited crew, trained and certified, they will be able to use it while at sea, as well. Read an interesting article on Bio diesel. They use it to run buses, here in the UK, especially in London. A lot of it comes from recycled fat and cooking oil, as well as fat waste from meat. However, bio diesel produced from soybean seemingly takes 800,000 gallons of water to produce 60 gallons of fuel, enough to fill the tank on a bus. In these days of diminishing fresh water, that's rather worrying. |
